Brembo 04-17 WRX STi/18-21 WRX STI Front GT BBK 6 Piston Cast 350x34 2pc Rotor Slotted Type3-Black

If you're looking to significantly upgrade your Subaru WRX STI's braking performance, especially for track days or spirited driving, this Brembo GT Big Brake Kit is a serious consideration. This kit replaces your factory front brakes with a much larger and more capable system designed to handle the heat and stress of demanding use. The 6-piston calipers and substantial 350x34mm two-piece rotors work together to provide more clamping force and better heat dissipation than stock components.

This Brembo kit features cast iron calipers, known for their strength and ability to withstand high temperatures. The calipers are paired with 350mm diameter and 34mm thick two-piece rotors. These rotors are slotted with Brembo's Type 3 pattern, which helps to keep the pad surface clean and reduce the risk of glazing, ensuring consistent stopping power even under heavy braking. The two-piece design also helps manage heat and can make rotor replacement simpler down the line. This setup is built to offer improved pedal feel and fade resistance, crucial when you're pushing your STI hard.

When installing a big brake kit like this, it's important to note that it often requires specific wheel fitment due to the larger caliper and rotor size. Always check the manufacturer's clearance diagrams to ensure your wheels will clear the new components. This kit is designed to be a direct replacement for the front braking system on the specified WRX STI models, offering a substantial upgrade for those who demand more from their vehicle's stopping power.
